To Replace Existing 3-Way Switch:
For wiring a NLV-603P, NLV-1003P, NLV-1503P, or NLV-2003P in a
3-way application, the wall switch has three screws; two of one
color and a third of a different color. It also has a green ground
screw.
Using the wire connectors provided:
• Connect the wire from the green ground screw to the green or
bare ground wire of the dimmer.
• Connect the wire from the odd color switch screw to the black
wire of the dimmer.
• Connect wire from one of the remaining switch screws to one of
the red wires of the dimmer.
• Connect wire from the last switch screw to the last red wire of
the dimmer.
6. Push wires into wallbox allowing room for dimmer to be
inserted.
7. Mount dimmer to wallbox using two screws provided and the
center mounting screw holes. Unit MUST be mounted
vertically.
8. Snap wallplate on over fins. When ganging, slide wallplate up
or down to align them.
